Z'palbwhom, may concci'nl Be it known that 1 JULIUS T. Dn Sooonn'r,

a citizen of the United States, residing at Ohicage, in the county of(look and State of Illinois, have invented. certain new and usefulImprovements in Iie-lP latos, of which the following is a full, clear,and sheet-specification.

lfllhis invention relates to improvements in 1 tieQplates interposedbetween railroad-rails I flanges or'ribs so arranged that when driyeninto the tie they expose the resulting brokendown fibers to saturationby water from rain and other causes, rotting and deteriorating the tieand correspondingly weakening and reducingits stability so quickly andto such an ex tent as to permit an objectionable shifting movement ofthe tie-plates and require the turning of a tie before it is otherwiseinjured in order that a sound surface may be presen;

ed to the tie-plate, all of which is not only 0 bj ectionably expensivein time, but in money. I

The object of my invention is' a tieplate so constructed that thelateral movement of railroad-rails held down spikes is substantially,ifnot entirely, resisted by the tie-plate and that the fibers brokendown b flangosor ribs-0n the tie-plate shall not be exposed to water orother elements tending to rot the fibers or reduce the stability of thef: tie-plate when in its operative position on the tie. a v

With these ends in viewrny invention. consists in certain features ofnovelty in the construction, combination, and arrangement of parts" bywhich the said objects and certain other objects hereinafter ap earingare attamed, all as fully desoribec with reference to the accompanyingdrawm s and more par tioularly pointed out in the c aim. in the said drawinge, Figure 1 IS a perspective view of a t1e-plate embodying my111vention with a part thereof broken away to'illustrate theconstructionby which fibers broken down by the ribs or flanges areisolated from moisture and with a portion of the rail in its operativeposition on the tie-plate against the abutment thereof. Fig. 2 isalongitudinal section of Fig. 1 on' a line longitudinall of thetie-plate and centrally through the rib thereof. Fig. 3 is a transversesection on the the as great as when the pistonline 3 3, Fig. 2. Fig. 4is a transverse section 55 Similar numerals of reference indicate the isame parts in the several figures of-the drawings.

wood tie havin 1 1ndicates an ordinar mounted thereon a tieQ'l a length,but of such Widt that its side flanges 3 may overlap and embrace theopposing 'sides of the tie, as distinguished from a tie-' platenarrowerin width and having its side flanges forced into the fibers ofthetie. The flanges 3 when embracing the opposin sides of the tiepreferably extend the entire ength te 2 of the usua'.

of the plate; but in tie-plates in which these tie-plates are narrowerthan the tie and the flw' ges are to be forced into-the fibers thereofthe flanges to cover and isolate from moisture the fibers broken downand crushed by the flanges are sufficiently shorter than the tie-plate,asillustratcd in Fig. 5, to enable the plate proper to projectsufficiently beyond forcing of the flanges into the body of the tie.

To further and more effectually isolate from moisture the. fibers brokendown by the flanges, said flanges 3 may be-in the natureof ribs-that isto say, inset sothat the sides of the tie-plate will project outwardlybeyond them; but whether so inset or not and whether or not theside-flanges are to be forced into the face of the tie, as illustratedin Fig. 5, or overlap the sides of the tie I also preferably provide theunder surface of the,

tieplate with arib 4 parallelwith and inter meciate of said sideflanges, which rib 4 is adapted to be depressedinto the fibers of thetie and terminate at a point inwardly removed. from. the ends of thetie-plate and a suflicient distance therefrom to enable the tie-plate toentirely cover and isolate frohi moisture. the fibers broken downidtorcing the rib 4 into the tie. 1 I By having the rib and the flangesshorter than the tie-plate their resistance when forced into the fibersof the tie to the lateral movement of the tie-plate is not onlypractically are extended to the ends of the tie-plate, ut the length oftime they may so resist this lateral movement is substantiallyincreased, for the reason that by the exclusion of moisture fromthebrokendown fibers they are prevented from, softening and finallyrotting, and thereby destroy tie-plate they will not deteriorate nor thetieplate loosen until the entire body of the tie is so nearly worn outthat its reversal and the shiftin of the tie-plate will not bejustified. As s own in the drawings, the rib 4 is triangular in crosssection, as obviously the form of the rib and also the flanges?) whenforced into the fibers of the wood is immaterial, exce ting so far asthis forcing may be facilitated and it is within my invention to formthe flanges and also the ribs in short and separated sections or in thenature of a series of teeth or points, if so desired. When the width ofthe tielate is such that the side flanges 3 embrace t e outer sides ofthe tie, said flanges may be curved or inclined, as indicated in Fig. 3,and forced to their operative position on-the tie after first slippingthe plate on the end of the tie, or, if desired, said flanges may be ofsufficient distance apart to rovide for dro ping the plate, so to speak,into place and a 'terward bending and forcing the points of the flangetightly against and even into the sides of the tie. On the other hand,the flanges 3 may be straight, as indicated in-Fi 4, or but slightlyinclined, so as to be force downwardly into their operative position, asindicated b the construction shown in Fig. 4. The tie-plate is providedwith the usual, preferably square, perforations 5, through which the sikes 6 are driven into the tie for holding bot the rail and thetie-plate in their operative position and against moving or creepinglongitudinally of the tie; but in order to relieve the body of thespikes 6 as much as possible from the pressure due to the lateralmovement of the rails and'increase the effectiveness of the s ikes forresisting the movement of the tiep ates both laterally andlongitudinally of the tie the lates embodying my invention are providedon their upper surface with ribs or other projections forming stops orshoulders 7, against which the outer edge of the 'base or flange 8 abutswhen the tieplate, the

' rail, and the spikes are in their operative po sition, which stops areso constructed and arranged as to substantially, if not entirely,relieve the body of thesplke from any lateral Contact with theraiLflange, while at the same time the head of the spike fully performsits function of holding the rail down upon the tie-plate and thetie-plate upon the tie, and therefore against vertical movement. To

faces in a line with and may be in advance of the side walls of theperforations which are parallel with and adjacent the rail-flange, sothat the lateral bearing of the rail-flange is substantially against thestops and not against the spike, or, in other words, so that the stopsto the substantial'exclusion of the spikes resist the lateral movementand pounding of the rail, and to these ends the sto or stops 7 may be ofany desired form an arrangementthat is to say, may consist of raisedrib-like projections extendin entirely across the tie-plate, butsectioned by the spike-perforations in the plate, or such stop mayconsist of a single enlarged lug or bar or a series of bars at a rightangle to and projecting against the edge of the railflange, for myinvention broadly includes any stop device on the upper su face of atie-plate, however formed or arranged, forming a bearing for therail-flange or its web and by which the moisture tending to rot thefibers broken down by the "ribs my invention extends to and includesside flanges of the tie-plate, whether one or both embrace the outersides of the tie, and also asimilar tie-plate narrower than the width ofthe tie on which it is placed.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is- I A tie-plate rovided withflanges projecting downwardly and inwardly over upon and closelyembracing the tie upon which it is used and having ribs provided withcutting edges on its under face at a point intermediate said flan es,said ribsterminatin at points inwardly removed from both on s ofthe'tie-plate, said tie-plate being also provided with spike-holes andhaving on its upper face a transverse rib or ribs, the bases of whichproject inwardly beyond the inner walls of the spike-holes, whereby atie-plate closely embraces both sides of a tie, moisture I is excludedfrom the broken-down fibers thereof and the lateral thrust of the railis re- JULIUS T.
